MACHINE FOR DRAWING AND SPINNING HEMP.

SPECIFICATION forming part of Letters Patent No. 317,117, dated May 5, 1885;

A Application filed July 18, 1884. (No model.)

To all whom it may concern.-

Be it known that I, J OHN Goon, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Machines for Drawing and Spinning Hemp or other Fibrous Materials, of which the following is a specification.

Although my invention is applicable generally to machines for drawing and spinning or twisting fibrous materials, it is more particularly intended for machines which are used for drawing and spinning or twisting hemp "for rope-yarns or twine.

The invention relates to a machine of the Jenny type, in which are employed one or more spindles and closed fliers for spinning or twisting the sliver and a catenary series of gill-pins, whereby the sliver is presented to the operation of the one or more rotary spindles and fliers.

In machines of this class the sliver is commonly passed or drawn through a nipper from the series of gill-pins, and thence passes directly to the rotary spindle and flier, and the spinning or, twisting of the sliver is performed between the bite of the nipper and the capstan-barrel or pulleys on the rotary spindle and flier. The nipper has been carried at the upper end of a lever, so that it will move slightly back and forth or away from and toward the spindle and flier as the quantity of material passing through it varies; and such movement of the nipper and its carrying-lever has been utilized to vary the speed of the series of gill-pins, so as to increase or diminish the delivery of sliver to the nipper. I have discovered that very superior results are obtained byreducing to a minimum the length of that portion of the sliver in which the spinning or twisting is performed; and to accomplish this is an important object of my invention.

The invention consists in the combination,

, with a spindle and flier, and means fordriv- I second nipper attached to and adapted to rotate with the spindle and flier.

The invention also consists in the combina tion, with a nipper through which the sliver is to be passed or drawn, and a stationary support, to which the nipper is secured in a fixed position, of a spindle and flier, means for rotating them, and a nipper attached to and adapted to rotate with the spindle and flier. Thesaid rotary nipper, which is attached to the capstan-head of the flier, preferably projects beyond the said head, and the jaws of the nipper form the extremity of the spindle and flier, and have a bite on the sliver or yarn close to the jaws of the stationary nipper. This construction also constitutes a feature of my invention. y

The invention also consists in novel details in construction of the two nippers, whereby they are better adapted for taking a bite on the sliver in close proximity to each other.

In the accompanying drawings, Figure 1 is a partly-sectional side view of a spindle and flier, and two nippers constructed and arranged aecording to my invention. Fig. 2 is a side view of the rotary nipper. Fig. 3 isan end view thereof. Fig. 4 is a longitudinal section of the nipper; andFigs. 5 and 5* are transverse sections on the dotted lines w m yy, Fig. 4. Figfigd is a plan View thereof. Fig. 6* is a horizontal section of the rear end of the nipper-stock. Fig. 7 is a longitudinal section of the fixed non-rotary nipper and an elevation of the spring-case.

Fig. 8 is an end view thereof, including a vertical section of the spring-case; and Fig. 9 is a side view of a portion of a machine embodying my invention, and illustrating the relative positions of the nippers in the machine. Figs. 2 to 8, both inclusive, are drawn to a large scale.

Similar letters of reference designate corresponding parts in all the'figures.

I will first describe the nippers which I have chosen to illustrate my invention, and the spindle and flier with which they are represented, reference being made particularly to Figs. 1 to 6*, inclusive.

A A"A designate the flier, which has hollow journals a a projecting from the heads A A; and B designates the'spindle, whichhas a long bearing in the tubular journal 11. and a bearing, 00*, in the head A. a

C designates the bobbin, which is fitted to the spindle, and is secured thereto by a bobbincoupling, 0, and a spring-actuated bolt or catch, 22.

On the hollow journal a of the driving-head A is secured a flier-driving pulley, c, and on that portion of the journal which projects beyond the pulley c is loosely fitted a spindle driving pulley, c, which is locked to the spindle B by interlocking lugs and notches c in a well-known manner.

The journal a is fitted to a bush, d, which forms a bearing therefor, and which is secured in a frame, F, of which a portion is shown in Fig. 1. On the outer end of this bush is formed a pinion, d, which is therefore fixed or non-rotary; and on the outer end of the journal at, which projects beyond the pinion d, is a capstan-head, D, on which is mounted a capstan-barrel, e, the shaft 6* of which is transverse to the axis of the flier. The shaft 6* is connected by bevel-wheels e c with a shaft, 0*, fitted in a bearing, -0 on the capstan-head D; and on the shaft 6 is a pinion, 6 which gears into the fixed pinion 01. Consequently, as the capstan-head is rotated with the flier, the shaft 6* receives rotary motion by reason of the gear 6 turning as it revolves around the fixed pinion d and transmits rotary motion to the capstanbarrel 6.

At the outer end of the capstan-head D is a socket, e, in which is fitted the rotary nipper G, which turns with the flier; and G designates the stationary or non-rotary nipper, which is secured in fixed position to a support which is here shown as an arm or bracket, f, projecting from the frame F. These nippers will bothbe fully described hereinafter.

The sliver s enters the nipper G, and thence passes through the rotary nipper to the capstan e,- thence through the journal a and be tween pulleys s in the head A and over one of said pulleys to a pulley, s and lengthwise of the flier to and over a traverse-guide pulley, to the spool or bobbin 0. The guidepulleys or traverse-guides s are pivoted to a ring-traveler, E, provided with sockets g, which slide on the rods A lengthwise of the flier, and in this way the traverse necessary to wind the yarn s on the bobbin 0 is obtained without moving the bobbin lengthwise of the flier.

semicircular sections provided at their adjacent ends with lugs or cars g and connected by bolts 9 and springs This construction of the ring-traveler prevents the sockets g from binding on the rods A of the flier in case the centrifugal force generated is sufficient to spring said rods.

The ring-traveler E may have a circumferential rib or tongue, 9*, to engage with a re ciprocating head movable on a guide parallel with the spindle and flier, and the motion of the head may be produced by a traversescrew-arranged parallel with the spindle and flier.

The ring-traveler is here shown as made in The construction and manner of operation of the spindle and flier form no part of my present invention, but are made the subject of my application for Letters Patent filed July 17, 1884, Serial No. 137,908.

The rotary nipper G projects forwardly from the capstan-head D, and its jaws form the terminal of the rotary flier and spindle.

The stock G of the nipper has at the rear end a spherical or half-round head, 9*, which is secured in the socket e by pivotal screws 9 the ends of which enter cavities in the sides of the head 9 and this connection gives the nipper freedom of motion and self-adj ustment. The stock is tubular for a distance from its rear end, but forward of that point it is cut away at the top and has a transverse section, as shown in Fig. 5. The front portion of the stock G* is notched across nearly to the under side at g, and forward and in rear of the notch 9 extends a longitudinal notch, 1 which is, however, not quite so deep as the notch 9 The notched end portion of the stock forms the fixed jaw of the nipper, and the seat for the sliver is the bottom of the notch 9 The movable jaw of the nipper consists of a block or piece, 9 notched on the under side,as shown at 9 and having a thin rearwardlyprojecting arm or shank, 9 which fits in the notch back of the notch 9. designates an arm, pivoted at one end to the stock (1* and pivoted at the other end to the arm or shank g of thejaw g thereby forming aloose connection, which provides for the free movement of the jaw g The force necessary to hold the jaw g to its work is furnished by a spring, 9, here shown as composed of a number of leaves pivoted at one end by a screw, to the stock, and at the outer end bearing directly on the back of the jaw 9 Being pivoted at g, the spring can be swung aside, as shown in Fig. 6, by a knob, g, and the movable jaw g and arm g can then be swung back on the pivot at the rear end of said arm, and the jaws can then be cleaned or inspected.

When in its operative position, the free end of the spring 9 bears upon the jaw 9 and is held against lateral displacement by small lugs or teats g on the under side of the spring, which snap over the shank g of the jaw g and form a catch sufficient to hold the spring in operative position.

It will be observed that the two jaws of this rotary nipper are at the extreme forward end, and hence it is enabled to take a close bite on the sliver.

The stationary nipper is shown in detail in Figs. 7 and 8. v

n designates the trumpet-mouth, the rear end of which is cut away to form a rectangular seat or holder, at, for the two jaws n n. The fixed jaw n consists of a notched piece, in which the movable j aw n is fitted. The fixed jaw of is secured in the j aw-holder n by screws w and the movable jaw a is pivoted at n to the fixed jaw.

n designates a spring-case mounted on an arm, n*, extending from the jaw-holder a,and the tension of the spring a in the case may be varied by a nut and screw, a a", connected with the upper end of the spring. Theforce of the spring n 'is applied by a lever, it", one end of which bears on the top of jaw a and with the other end of which the spring a? is connected. The lever it enters the case through a slot, at, and when its one end is pulled up by a spring, a", its other end is depressed and holds down the movable jaw 01. The top of the slot n forms a fulcrum for the lever a and lateral movement of the lever isprevented by a pin on the top of the movable jaw.

It will be observed that the jaw-holder and jaws nrfi a form a square end to the nipper, and the rotary nipper being also square-ended the two can work so close together as to be almost in contact.

Fig. 9 represents a portion of a machine in which are employed eight spindles and fliers, arranged in two groups, one above the other, with four spindles in each group. This arrangement gives four spindles and fliers in each vertical tier, and the side elevation,Fig. 9, shows the spindles and fliers of one tier.

F F designate the two upright frames,in the former of which are formed the bearings for the hollow flier-journal, a, and in the-latter of which are secured the bushes d, which form the bearings for the flier-journals a.

The sliver to be spun or twisted is supplied to the spindles and fliers of the two vertical tiers by two catenary series of upright bars and gill-pins, which are connected with and carried or moved by chains moving in horizontal planes. A portion of the series of upright bars or rods h, with their gill-pins h and 'moving chains h, which supply sliver to the vertical tier of spindles shown, is also shown in Fig. 9. The upper and lower ends of the upright rods or bars h move in and are guided by upper and lower tracks or ways, h if, and the chains are moved by chain-wheels on vertical shafts at the ends of the two series.

The vertical shaft h, for driving one series of upright rods or bars and their chains, is here shown, and the vertical shafts for both series are driven by bevel-gearing If from a cross'shaft, h", which itself receives motion by worm-gearing'h from a shaft, h

As before stated, the stationary nippers G are supported on brackets f, which extend from the frame F, and as there are four spindles and fliers in each vertical tier there are also four stationary nippers supported one above another in positions to operate in conjunction with the rotary nippers G of the four spindles and fliers. In the end of the lower track or way, hflwhich is adjacent to the spindles,is a drop, 79*, and as the vertical rods or bars h arrive at that point they fall vertically sufficiently to withdraw the four series or tiers of gill-pins, h*, from the slivers and permit them to sweep round under the stationis shifted to stop and start the machine by means of a screw, 1', having at its head alever or arm, & connected by a rod, i with a lever or arm, i on a rock -shaft, t The rock-shaft is to be operated by treadles to stop and start the machine, but such stopping and starting gear is shown and described in my abovementioned application, SerialNo. 137,907,

a and is not here claimed.

The driving-pulleys c of the flier in the upper and lower groups are operated by belts j j, which partly encircle them and receive motion from themain shaft H. The spindledriving pulleys c are operated by two belts, j 9', also from the shaft H, and these belts not only partly encircle the spindle-driving pulleys 0, but also pass around upper and lower teusion-pulleys, 7' j*, which are drawn apart to put more tension on-the belts as the windingof the bobbins proceeds. This belt-drag and the means for drawing or moving the ten sion-pulleys j' j apart to put more tension on the pulleys j j form the subject of my appli cation for Letters Patent, filed July 19, 1884, Serial No. 138,161; and I will only say that the shaft j and parts designated by the letter are portions of the mechanism for regulating the tension of the belts; and j is a tell-tale for indicating the tension, all of which parts are described in my said application.

The shaft h is rotated by a belt, h, and pillleys h? h from the driving-shaft H, and the shaft h through worm-gearing h, imparts motionto an upright shaft, I.

Midway between the upper and lower;

groups of spindles and fliers is a traversescrew, J, here shown as having a compound ment of each head K along. its guide-rodv thereby produces the reciprocating move- .ment of all the traverse-rings E which engage with it along their fliers.

0n the traverse-screw J is fitted acarriage,

I 1 5 or crossed thread and rotated continuously in L, having in it a swiveled nut, whereby the compound or cross-threaded screw rotating continuouslyin one direction produces the reciprocation of the carriage.

The reciprocating carriage L has upwardly and downwardly extending arms m, which are forked to fit annular grooves in the hubs of the two circular heads K, and by such connection the heads are reciprocated with the carriage, while still free to rotate with the traverse-rings engaging with them.

The construction and arrangement of traverse mechanism for a number of spindles, as above briefly described, is clearly shown and described in my aforesaid application, Serial No. 137,908,.and I here make no claim thereto.

What I claim as my invention, and desire to secure by Letters Patent, is
